| 설명 | 눈을 가지고 정확히 보아 식별할 수 있는 능력이다. 시력표를 이용하여 측정한다. 5m밖에서 시력표를 보아 2/3이상 읽을 수 있는 최대시력을 시력으로 정한다. 정확한 시력검사는 산동제를 투여하여 눈의 조절을 막고, 검안경으로 검사해야 한다. |

| vernier | A short scale made to slide along the divisions of a graduated instrument, as the limb of a sextant, or the scale of a barometer, for indicating parts of divisions. It is so graduated that a certain convenient number of its divisions are just equal to a certain number, either one less or one more, of the divisions of the instrument, so that parts of a division are determined by observing what line on the vernier coincides with a line on the instrument. Vernier calipers, Vernier gauge, a gauge with a graduated bar and a sliding jaw bearing a vernier, used for accurate measurements. Vernier compass, a surveyor's compass with a vernier for the accurate adjustment of the zero point in accordance with magnetic variation. Vernier transit, a surveyor's transit instrument with a vernier compass. Origin: So named after the inventor, Pierre Vernier. Source: Websters Dictionary (01 Mar 1998) |

| Vernier, Pierre | <person> French mathematician, 1580-1637. See: Vernier acuity. (05 Mar 2000) |
| absolute intensity threshold acuity | The minimal light that can be seen. (05 Mar 2000) |
| acuity | <ophthalmology> The clarity or clearness, especially of the vision or hearing. Origin: L. Acuitas = sharpness (18 Nov 1997) |
| visibility acuity | The recognition of an object on a background of different character. (05 Mar 2000) |
| visual acuity | <microscopy> The ability to detect fine details or small distances with the eye. Visual acuity can vary substantially depending on the definition used and method of measurement chosen. Under favourable conditions, the resolution of the human eye or ability to distinguish the twoness of adjoining lines, is about I minute of arc while the threshold delectability, or the detection of misaligned steps in a line (which is also a form of visual acuity), can be as low as a fraction of a second of arc. (05 Aug 1998) |
| resolution acuity | The detection of a target having two or more parts, often measured by using the Snellen test types; indicated by two numbers: the first represents the distance at which an individual sees the test types (usually 6 meters or 20 feet), and the second, the distance at which the test types subtend an angle of 5 minutes; e.g., vision of 6/9 indicates a test distance of 6 meters and recognition of symbols which subtend an angle of 5 minutes at a distance of 9 meters. Synonym: visual acuity. (05 Mar 2000) |
| spatial acuity | The detection of the shape of a test object; e.g., perceiving polygons of the same size but with different numbers of sides. (05 Mar 2000) |
| stereoscopic acuity | The detection of differences in distance by superimposition of slightly different retinal images into a single image to the brain. (05 Mar 2000) |
